Equilibrium characterization, magnetic susceptibility and fluorescence measurements proved that the silver (II) porphyrin complex formed in the reaction of the Ag+ ion and the 5,10,15,20-tetrakis(4-sulfonatophenyl) porphyrin ligand is of sitting-atop (SAT) type. The complex also exhibits typical SAT features as regards its photoredox degradation reactions, which might be utilized in photodynamic therapy. On the contrary, the corresponding gold(III) porphyrin is unambiguously of planar structure, which does not show any fluorescence and photoinduced degradation. The deviating structures, and hence, photoinduced behaviors of these complexes can be attributed to the effect of the different ionic radii (r(ion)(Ag2+) = 94 pm; r(ion)(Au3+) = 85 pm).
